FiveThirtyEight, a data journalism website, has created a visualization tracking players’ advantages in the 2021 World Chess Championship. In the visualization, a line moves up or down towards the players according to their chances of winning the match after each move. The area between the dynamic line and center line is shaded red or blue to represent each player. For example, in Game 6, the line moved frequently between the two players, reflecting the closeness of the match. However, one player missed a free pawn and the line shifted towards his opponent, who eventually won the game.
